SPECIFICATION forming part of Letters Patent No. 633,842, datedSeptember 26, 1899. Appiicatior filed March 31, 1898. Serial No.675,890. \llc model.)

To (all whom, it In/c1. GOG/00771.;

Be it known that I, JOHN A. IIOFF, a citi' zen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

have invented anewand useful Improvement in Cash Registers andRecorders, of which the following is-a specification.

My invention relates to an improvement in the class of key-actnateddevices employed IO for the purpose of showing theamount of cash whichshould correctly be found at any time to be contained in the machine bythe machine being caused to register each time it is operated, as bymoving a drawer or otherr5 wise. Asthis is an important function of myimproved machine, it may properly be classilied as a cash-register,though it is also adapted to perform various other functions,

preferably those of recording on checks to be delivered to customers theamounts of sales,

recording credit sales, recording amounts paid out, and causing theregister to account for amounts paid out by showing the remainder ofcash that should be contained in the machine. Although, therefore, Ientitle my invention an Improvement in cash registers and recorders, Iintend to be included therein any machine of the same general characteradapted to be operated to show transactions whether by registering orrecording or both registering and recording the items in amounts, withor without other matter of information. In this connection it should bestated that my improved machine may also be used for weights andmeasures as well as for money.

The primary objectof my invention is to enable the registry of anydesired maximum amount to be produced with the smallest pos- .to siblenumber of actuating-keys-that is to say, to enable any amount to beregistered with my improved device no more than ten keys are required,each representing adil'ferent numeral, say in the series 0 to 9.

5 The principle I employ to this end forms the gist of the registryfeature of my invention. It involves the use under control of the keysof reciprocatory bars or rams, one being provided for each decimal placeor value po- 0 sition of a digit within the registry capacity of themachine whet-her it be of amounts rep resented in two or in any greaterseries of cligitwalue positions. As the money denominations of mostcountries are in accordance with the decimal system, I refer to thedecimal series of the moneyvalue positions throughout the explanationhereinafter contained, though it will be understood that my improvementmay beused equally well for registering other divisional moneydenominations, such as pounds, shillings, pence, farthings, the.Toillustrate, the registry capacity of the machine represented in thedrawings is of amounts expressible in four figures. Accordingly fourrams are provided, being supported on a carriage in horizonal series andin normally-retracted position. By depressing any keyand each keyrepresents a number, which should be conspicuously displayed upon it-thefirst of the series of rams 7o shoots out a predetermined distance andreleases the carriage to enable it to move and carry the projected raminto position for proper engagement with register-actuating mechanism,whereby when the rain is re turned into the carriage, as by opening acashdrawer, operating a lever, or otherwise, it works the register.

An important peculiarity of my improved machine with the minimum numberof keys 8a is that of registering the amounts in the direction in whichthey would be writtenthat is, from left to right-whereby confusion ofthe operator is avoided.

Another desirable function of the machine is that of recording theamount of each sale, which is performed by the operation which producesthe registering action. For recording credit sales mechanism is providedunder the control of a separate key, and a separate 0 key is providedfor producing a record of each amount paid out of the machine and forcausing the register mechanism to show, by actuating it in the mannerhereinbefore oiitlined, the remaindcr of cash in the machine 5 afterpaying out.

In the accompanyingdrawings, Figure 1 is a plan view of my improvedmachine; Fig. 2, a section taken at the line 2 on Fig. 1 or at the line2 on Fig. 4 and viewed in the direction of the arrow; Fig. 3, a sectiontaken at the line 3 on either Fig. 4. or Fig. 5 and viewed in thedirection of the arrow; Fig. 1-, a section taken at the line At on Fig.2 and viewed in the direction of the arrow; Fig. 5, a section taken atthe line 5 on Fig. 2 and viewed in the direction of the arrow; Fig. 6, asection like that presented by Fig. 5, but omitting the mechanism abovethe sectionline on the last-named figure if that line were projectedstraight through the length of the machine from the point at which itbegins; Fig. 7, a bottom plan view of the mechanism illustrated in Fig.(3; Fig. 8, a view in elevation of the rear-end portion of the leverdevice, against which the rams successively abut; Fig. 9, a broken viewshowing the carriage and rams in front'end elevation; Fig. 10, a sectiontaken at the line 10 on Fig. 2 and viewed in the direction of the arrow;Fig. 11, a sectional view illustrating parts presented by Fig. 3, butshowing the first or advance ram released and thrown out to producemovemen to'fthe carriage; Fig. 12, asimilar view showing the aforesaidram brought by the mm ementof the carriage into relation with mechanismwith which it will be caused to cooperate by openingthe cash-drawer;Fig. 13, a broken section taken at the line 13 on Fig. 1 and viewed inthe direction of the ar row; Fig. 1 a plan view of the registeringmechanism; Fig. 15, a section taken at the line 15 on Fig. lat andviewed in the direction of the arrow; Fig. 16, a broken section taken atthe line 1b on Fig. 1 viewed in the direction of the arrow and enlarged,or taken at the line 16 on Fig. 15 and viewed in the direction of thearrow; Fig. 17, a section taken at the line 17 on Fig. 2 and viewed inthe direction of the arrow; Fig. 18, a section taken at the line 10' onFig. 2 and viewed in the direction of the arrow; Fig. 1.), a view infront elevation of a perforated paper check; Fig. 20, a top plan view ofone of the number-recording arms; Fig. 21, a similar view of thelegend-recordingarm; Fig. 22, asec-tion taken at the line 22 on Fig. 1,viewed in the direction of the arrow and enlarged, showing the keyconstruction; Fig. 2-3, a section taken at the line on Fig. 22 andviewed in the direction of the arrow; Fig. 2-1, a bottom plan View ofthe recording-lever; Fig. 25, a similar View of the pivotal tearing-bar;and Fig. 20, a view like that presented by Fig. 9, but showing amodification in the register-operating mechanism.

The case A may'involve generally the conventional form of key-operatedcaslrregister case, with the keys A on the shelf portion at the forwardend, and in the bottom of the case is the usual sliding cash-drawer Awhich I prefer to use in my device, though other means may, ashereinbefore suggested, be substituted for operating the internalmechanism hereinafterdescribed. The cover A" is shown to be hinged atthe rear end of the case and adapted to be locked at the opposite end,and between its ends it is formed with a table-section A at aninclination con venient for writing. The drawer is housed in a lowercompartment formed in the case, with a false bottom or diaphragm Aprovided therein.

Transversely of the case and forward of its center there extends a rodr, on which is sup ported asleeve r, carrying at its forward sideratchet-teeth? and forming the sliding hearing for a carriage B. shownas of rectangular shape, with a series of fourlongitudinal dovetailgrooves in its upper side, in which the rams B are confined. The normalposition of the carriage is at the right-hand side (relative to thefront of the machine or end at which the drawer pulls out) of thelongitudinal center of the case, and it is yieldingly held there by thetension of a spring r fastened at one end intermet'liately, ashereinafter described, to the carriage to extend transversely across itsbase and at its opposite end to the false bottom A at a lugr, projecting therefrom, Fig. 1. A bell-crank lever r fulcru med at its angleto the false bottom, has the free end of the spring 1- connected with itto one side of its fulcrum and is pivotally connected from the free endof its longer arm by a link r with the bottom of the carriage, thebell-crank and link thus forming the intermediate connection referred toof the spring with the carriage. On the shorter end of the bell-cranklever is fulcrumed a dogi, controlled by a spring 1' and serving apurpose hereinafter described. Each ram B is provided at its forwardextremity with an upward-projecting tooth 0", shown beveled on its rearside, and at its opposite end with a depending finger r from which it isconnected with a corresponding finger r, depending from the base of thecarriage, by a spring a, tensioned by retracting the ram in the groovein the carriage to tend to throw it out when released. Onthe upper sideof each ram are provided a series of rackteeth r (shown as ten innumber,) and be hind them the saute number of ratchet-teeth r, and atthe under side of the rear end of each ram but the first, or that at theextreme right-hand side, it is recessed, as shown at 0', Fig. 7, to seatslidingly upon a rigid detent or holder 9', projecting upward insuit-able position from the false bottom A The keys A (shown as ten innumber and as numbered successively from O to .9) work thi oughopeningsin the shelf at the front of the case, where they arespring-supported to maintain them normally in their elevated positionssubject to depression and to rebound on being released from pressure toan extent limited by a stops on each key. All the keys A are of the sameconstruction. (Shown most clearly in Fig. The stem of the key iscentrally recessed from its lowercnd to, say, near its transversecenter, where there is pivotally supported in the recess aspring-controlled finger q, affording a power-transmitter, as and for apurpose hereinafter described, provided at its opposite edges,respectively,

with the projections q and the projection q normally protruding at theforward edges of the lower cut-away portion of the key-stem. At theirlower en d portions the key-stems pass freely through guide-openingsprovided in an angle-plate g supported from the under side of the shelf.

ings on the sides of the case near itsforward end, is fastened a leverO, formed of arms 1) 19', carrying between them a platep extended fromits rear edge near the center into a tongue 19 from which there dependsa rigid stop f. The arms 1), which are normally maintained in theirraised horizontal position by a spring 29 confined against the tongue pfrom underneath, are provided on their inner sides, above the plane ofthe plate 19 with longitudinal guide-grooves 13 in which is confined aslide-plate 0, provided with a rearwardextending tongue p coincidingwith and overlying the tongue 19 and provided, near its outer extremity,with air upward-projecting lug from which it is connected with the rearwall of the case by a spring 17 of lighter resilient force than eitherspring r The forward edge of the plate O is formed on an incline andpresents ten offsets or steps, (marked in series from O to 9 tocorrespond with the keys with which they respec tively coincide.) In theplate 12 are provided openings shown to be of square form in seriesextending lengthwise of the plate. These openings are marked insuccession from 1O to 19. keys A above them and coincide with theoffsets on the forward edge of the plate C. Another plate O is pivotallysupported near its opposite ends from the bottom of the plate 19 byparallel links i and f, the link i being extended to form a bell-cranklever carrying pivotally at its end a spring-pressed dog 6 whichprojects normally into the path of the teeth of the carriage-ratchet rand passes through a bearing i Fig. 8, in the stop 1).

tends through a bearing i a spring-pressed supplemental dog t, engagingat its free end with the carriage-ratchet.

From the description thus far of the mechanism the operation will beunderstood to be as follows: By depressing a key A-say that marked 5 inthe passage of the lower end of its stem through the coincident opening15 in the plate-lever p the projecting part (1 of the transmitter qbears at its lower end at the edge of the opening against theplate-lever, thereby depressing the latter against the resistance of thespring 19 and removing the forward end of the tongue p out of abuttingThey respectively aline with the 3 In shooting out the ram encountersthe tonguep of the slide-plate O, thereby forcing it forward till theoffset 5 in its opposite edge engages the projecting portion g of thetransmitter (I on the key 5 and presses it inward, to project,accordingly, the part g at the opposite side of the key into engagementOn a shaft 1), journaled at its ends in bear- Z engagement with theadjacent end of the first ram B, which in the normal position of the 5carriage is held retracted in its recess in the 1 latter by stoppageagainst the tongue 29 The moment therefore that the plate is depressedby depressing a key the first ram otal dog-controlling plate O 1 meansof a link 0 with the adjacent edge in its path of the piv- As the part(1 of the transmitter recedes it enters the plane of the opening 15 inplate f. The force with which the transmitter encounters the tongue onthe plate 0 moves the plate outward a sufficient distance to withdrawthe dog 25 from from the path of the ratchet 1' thereby permitting thespring 2" to draw the carriage, with the first of the series of rams inits projected condition, toward the left-hand side of the machine untilthe motion is arrested by the supplemental dog f encountering the end ofthe bearing through which it passes. As will hereinafter be seen, thesubsequent retraction of the ram works the register.

Extending across the interior of the case near its center is a rod 0,carrying toward the left of the normal position of the carriage a set orbank of segmental racks D, corresponding in number and distance apartwith the rams B and each having ten teeth. Each segmental rack has abackward-extending portion 0', terminating in a head 0 and anupward-extending arm 0 of segmental shape at its extremity, where itcarries a series of numbers, from 0" to 9, formed in out line,preferably with perforating-points. These are represented most clearlyin Fig. 20. On the head 0 of each extension 0 are fulcrumed at theirangles, to extend in parallel relation to each other, a pair ofbell-crank le vers 0 0 one of which is spring-pressed, and both arepivotally connected together by At the ends of the longer arms of eachpair of these bell-cranks they are pivotally connected with lugs 0projecting from one side of a curved slot-link D, From the bottom of theplate 19 there also exprovided on its opposite inner sides with seriesof teeth 0 and 0*, each series comprising nine teeth.

E is the register, preferably of the lascal type, involving thefollowing construction:

About a stationary rod u, extending across the case nearits rear end,are formed throughout a portion of the length of the rod a series of tenflutes u at equal distances apart. On the fluted part of the rod arerotatably supported a series of wheels n each numbered 0 to 0 about itsrim, seven of these being shown, though more or fewer may be provided.As shown, each wheel a has its perimeler extended asa rimlaterallytoward the left to afford the surface for carrying the numbersand to render the wheel reentrant or annularly open at one side, and atthe closed left side of each wheel and formed by preference integralwith it is a ratchetu containing a spring-controlled brake-tooth ashoots out under the recoil force of its spring projecting through theratchet into the plane of the llutes a. ltach ratchet it extends for ashort distance past or laps the annular rim of the next adjacent wheel,in which it abuts against a spacing-disk 12 provided. in'itscircumt'erential edge with a recess a of alength equal or aboutequal to the width of two spaces between ratehet-teeth. The oppositeends of the recess in each spacing-disk are slightly beveled orcam-shaped, as shown at n in Fig. 15. To the inner surface of the closedside of each wheeln is pivoted a springpressed pawl a terminating at its"free end in a lateral extension or linger n", shown as of approximatelyrectangular cross-section and long enough to enter the recess rt ol'theadjacent disk a and also engage with the teeth of the ratehetn next tothat disk. The disks a are stationary, being so maintained by keys n(see Fig. 15,) extending from them into engagement with a flute in therod 02, and the members of the register are confined in place on the roda between collars n 01 lVith the understanding that the recesses n inthe successive disks n permanently coincide with each other and that apawl 11 is only in a recess a when its wheel registers O or has made acomplete revolution the working of the register irrespective of themechanism I employ for operating it, but which is hereinafter explained,will be comprehended from the following description: lVith the pawl a onthe units-wheel or that at the extreme right of the series of wheels inthe position shown of the pawl in Fig. 1-3, (and which may for thepurpose of explanation be presumed to be in the recess of the nextadjacent disk 11 and the teeth of the tens-wheel ratchet,) turning theunits-wheel ratchet n -say, in the direction of the arrow on Fig.15-rides the pawl-linger on the units-wheel out of the recess a up theadjacent cam end 02 thereof, thus without disturbing the tens-wheel 01until the units-wheel shall have made a complete revolution. Then thepawl-finger of the units-wheel will have reached and have dropped intothe recess of the first disk if, being thus brought into the plane andin front of the tooth ot' the second ratchet-wheel,which is presentedbetween the ends of the recess, so that the next turn of the units-wheelto or beyond the within one complete revolution will turn the tens wheelthe extent of one tooth of its ratchet or until the finger of the pawlon that wheel again reaches the position shown in Fig. 15. Each completerevolution of the units-wheel brings its pawl-linger into the recess ofthe disk of the tens-wheel against the middle tooth of the ratchet therepresented to cause the tens-wheel to be turned one tooth. In the samewayeach complete revolution of the tens-wheel produces one-tenth of arevolution of the hundreds-wl1eel,and so on throughout the series. Thekeys A are depressed in the order of the occurrence from left to rightceases of the ligures in the amounts to be registered. According to thearrangement of the mechanism in the present machine, as illustrated, noprovision is made, though it could be, for registering any amountgreater than is expressible with four figures, thus either andpreferably fromiens of dollars to cents or from thousands ol. dollars todollars. After depressing all the keys required to express the amount tobe registered the next operation is to pull out the cash-drawer A Forthe purpose of the explanation in the present connection it may bepresumed that only one key has been depressed to denote a sale in anamountexpressible in nnitsof cents. As hereinbefore explained, this keydepression has released the lirst ram 13 and caused the carriage to moveone step. The movement of it re carriage brings the projected ramcoincident with the first segmental rack D, as shown in Fig. 112. Theteeth 0" on the ram slide into engagement with those on the rack by thedescribed movement of the carriage. The distance to which the ram isshot out is determined by the offset in the plate C which it encounters,and that determines the tooth in the series thereof on the ram whichengages the extremeorinnermosttooth of the rack. Thus it the key be theone depressed the lirst ram will be projected far enough to bring itssixthtooth (counting from the li'orwari'l ram end) against the back ofthe innermost tooth on the first rack D,whereby when the ram is forcedhome in its carriage it will turn the rack the extent of six teeth, withthe result hereinafter described.

In the case, near its forward end, are journaled, to extend transverselyacross it, two parallel shal'ts lit and m, carrying, respectively, thcdrums in? and H1", in alinement with the set of segmental racks D. Aboutthe drums there extends an endless apron in", formed, preferably, ofmetal, to be driven by rotation of the shafts and provided withprojecting rigid abutments m, m, m and m, in number corresponding withthe number of rams, thus four in the present arrangement, placed atequal distances apart about the apron on dillferent planes, respectivelycoinciding with the different segmental racks, and thus with therespective rams when each is brought into engagement with a differentone of the segmental racks. The shalt m carries loosely on one end atthe right-hand side of the case a pinion in), provided at its inner sidewith an enlargement in the form of a disk m on which is pivoted a springpressed dog at to engage with a notch (indicated at m in 3) formed inthe shaftm. On the rod 0 is fulcrumed at its angle coincidently with thepinion in", a bell-crank lever Z, Fig. 3, yieldingly connected from itsshorter arm with the back of the case by a strong spring Z and bearingat a thimble Z on the extremity of its lower arm, against a shoulder onthe rear end of the drawer A ICO . mental rack Z against the pinion m"to rotate teeth 0 (or 0 is so timed that when the rack Connected orintegral with the bell-crank at its angle to move with it is a segmentalrack 1 meshing with the pinion m.

To pull out the drawer A by the grip, (shown at u,) it is first unlockedby lifting the spring- I bolt t" at the handle c In the opening movementof the drawer the spring Z causes the thimble end of the lever Z tofollow the drawer, thereby turning the lever on its fulcrum andsimultaneously turning the segit, and, through the engagement ofthe dogmwith the shaft m", turn the latter through two complete revolutions andwith it the apron.

The projected ram B being in the position in which it is represented inFig. 12 and in which it is held by a pivotal spring-pressed dog w,engaging the ratchet-teeth 7', (one such dog being provided for eachram) is in the path of the abutment 121 on the traveling apron, whichaccordingly upon a complete revolution forces the ram back in its groovein the carriage, with the result of turning the segmental rack D,withwhich the ram engages, the extent of six teeththat is, from the 0 toothto the 5 tooth, so to speak. The dogs 20 hold the rains by theteeth ratevery point in their backward movement. This turning of the rack Dlifts the slot-link D, connected with it, till five of its rack-teeth ohave engaged live teeth in their path of the ratchet n of the register,thereby turning the ratchetthe extent of five teeth to display thenumber 5 upon it if the 0 were previously displayed. lhe movement of theleading D turns the extent of any number of teeth the ratchet n will beturned one tooth less. If two, three, or four of the keys Ahave beenstruck, the dog 6 will have been released from and engaged with theratchet 4 a correspond ing number of times to permit the spring 7- tomove the carriage step bystepaecordingly and project at each a ram to bemoved sidewise with the carriage into engagement with a segmental rackto the extent of the number of teeth corresponding with the number onthe key depressed to efieet its projection. The dog is placed so high inthe plane of the teeth r that each time the tongue rises to resume itsnormal position, while the dog 15 engages the teeth to hold thecarriage, the dog if clears the ratchet-teeth to be retracted by itscontrolling-spring for a fresh grip,when the plate P2 is again depressedby actuating a key. In each step movement of the carriage a ram B, afterthe first, is released by being slid at the recess in its rear end offthe retainer 7".

If, say, by way of explanation, it be de sired to register by themachine a sale of forty-five dollars and eighty-three cents, four i ofthe keys A will be depressed in the order 4, 5, F, 3. \Vith the firstkey depression 1 the first ram will be projected the extent of l fiveteeth and will be moved by the carriage \Vith the under the firstsegmental rack D.

second key depression the carriage will move another step, bringing thefirst ram under the second segmental rackand the second ram, previouslyreleased from its retainer 0' to permit it to project the extent of sixteeth, under the first segmental rack. \Vith the third key depressionthe carriage will move another step, bringing the first ram under thethird segmental rack, the second ram under the second rack, and thethird ram, previously released from the retainer to be projected theextent of nine teeth, under the first rack. lVith the fourth keydepression the carriage will move another step, bringing the first ramunder the fourth segmental rack with five of its teeth behind theadvance rack-tootl1,bringing the second rain under the third rack withsix of its teeth behind the advance rack-tooth, bringing the third ramunder the second rack with nine of its teeth behind the advancerack-tooth, and bringing the fourth ram, pre viously released from theretainer 1", under the first rack with four of its teeth behindtheadvance rack-tooth. Vhile the carriage is moving laterally the dogs aform a species of track for the teeth 1-, which they engage, to hold therams in their severalprojected positions until retracted, as hereinafterdescribed. It will be understood that the retainer 1' is shorter thanthe width of the carriage by the width of one ram, so that the firststep movement of the carriage already slides the second ram off theretainer to abut against the tongue and be held from shooting out tillthe second key is depressed. Thus the first ram is normally retained bythe tongue p and each succeeding ram is normally retained by theretainer '2' and successively by the tongue to effect the release ofeach in turn by depressing a key. It will also be understood that when aram is projected and the carriage is moving the tongue 1), which isnarrower than the distance between the longitudinal centers ofsuccessive rams, has time to rise under the action of spring 2) and toget up to oppose the ram before it has moved entirely ell the retainer r\Vith the four rams engaging the segmental racks in the mannerdescribed, opening the drawer permits the spring Z to act upon the leverZ and rack Z to rotate the shaft m twice around, thereby actuating theapron m once around and causing the abutments on the apron to encounterthe four projected rams and shove them, one at a time, back in theirgrooves in the carriage. The arrange ment is such that no two rams aresimultaneously under retractive motion, the abutments on the apron beingso placed that the ram in the path of abutment m is moved first,followed in successionby the rams in the paths of abutmentsmfl m and012. Thus the four segmental racks D will each be turned as far as thenumber of teeth on the ram engaging it will move it and willcorrespondingly move the four slot-links D, the

fourth to engage four teeth 0 with its ratchet a of the register E, thethird to engage five of these teeth with itsratchet, the second toengage eight of the teeth with its ratchet, and the first to engagethree of the teeth with its ratchet. In this way, if at the beginning ofthe operation the register were setat O, as it may be at the end of eachday-that is the series of ringsthe described operation I l l l will. beout of coincidence with the recess be depressed.

By the step movements of the carriage l3 the short dog Won the upperside of the shortarm of the carriage-spring lever is protruded fartherand farther byeach step moveto say, with a row of ciphers displayed on 13 lever Z.

of the mechanism will cause the register to 1 display the number 4,583.thereafter repeated by depressing one or eration of theregisteractuating mechanism under the opening movement of the drawer, beshown by the register in the sum of such amount added to the amountpreviously on the register wheels. The same operation which has effectedraising of the slot-links D, or any of them, turns each arm 0 on asegmental rack .D a corresponding distance to bring theperforating-number of the series thereof on the segment-shaped end ofthe arm 0 into coincidence with an opening in the cover A at the base ofthe table-section A therein. In this opening is supported aspring-pressed lever F, fulcrumed on cars 0:, depending from the underside of the cover near one end of the opening and having at one end anarm 75, extending forward with relation to the keyboard of the machine.

.The width of this lever should be at least that of the bank orseries ofarms 0 to extend across their plane, and it is provided on its lowerside, near the rear edge, with a longitudinal recess 7a, Fig. 13, intocoincidence with which the number on the head of each arm 0 to beperforatingly recorded is brought by actuating the register mechanism inthe manner described. Adjacent to the lever F there is journaled on thecover A at the forward end of the case, a roll G of record-paper, oneend of which is passed across the recess 7b" in the lever F, out throughthe opening alongthe top of the cover, under a springpressed tearing-offlever H,fulcrumed on the cover in a depression H therein, by which toenable the operator to get with his hand under the tearer to grasp thepaper for drawing it out after it has been written on at the table A"and preparatory to tearing it off to afford a check to be handed thecustomer or for other purpose.

In the upper edge of the left-hand side of the drawer, near its forwardend, is a recess i to receive, when the drawer is closed, a stop 1" onthe end of a spring-messed lever 2' which extends directly underneath anarm i extending from one end of the rockshaft 17. \Vhen the lever-platepis depressed by actuating a key A, the arm 2' is simultaneouslyturnedagainst the lever t to depress it and hold the step t" in the recess tto prevent the drawer from being opened prematurely. Moreover, when thedraweris opened no ram can be operated, since then the stop Each amountI 1 it yields in that direction. more of the keys A will, bythedescribed op ment into the path of the primary actuating- As the draweris pulled out the lever Z, which works through a slot l in the falsebottom 4.1 freely passes the dog r as \Vhen the lever Z reaches theforward end of the slot Z, it is stopped, while the drawer continues inits opening movement.

A thrust-rod 71., having a laterally-extending rigid finger 71," for apurpose hereinafter described, is supported in per 'iendicular posiiionto adapt it to move up and down, with its upper end extending againstthe springpressed arm 7; of the lever F, and on its lower end this rodcarries a shoe 71 beveled on its under side, Fig. 2, and held normallyin alinement with the red by a spring 71 The shoe 71. projects into alongitudinal recess 7t, formed in the upper edge of the left-hand. sideof the drawer and beveled at its rear extremity to form a cam end 71.,corresponding with the bevel on the shoe 7L2. When the lever Z isstopped at the forward end of its slot in the false bottom A the cam endof the sloth" has reached the shoe H2, and by continuing the openingmovement of the drawer the cam 71, by its engagement with the shoe,forces the thrust-rod ft up against the arm 1.: of lever F, therebydepressing the recess 7.; thereon against the paper and pressing thepaper against the number or series of numbers brought coincident withthe recess, as described, and formed preferably with perforating-points.In this way the number struck bydepressingone or more keys A will berecorded on the paper, which when torn off affords the check I. (Shownin Fig. 19.)

Alongthe bottom of the right-hand side of the interior of the case thereextends a rack g, and coincident with this rack there is supported toyield in both directions a springdog g on the rear end of the drawer.

With the drawer pushed in to its full extent the dog g depends andrights itself in a recess bet hind the rack, and a similar recess g isprovided at the front end of the rack to admit the dog and permit it torightitselt' when the drawer is fully drawn out. In pulling out thedrawer the dog rides at an angle over the rack, but obstructs anyattempt to close the drawer till after it shall have been fully opened,and in the closing operation of the drawer the dog also rides over therack at the opposite inclination to prevent opening the drawer till itshall have been fully closed. The dog and rack afford a safety devicefor preventing the operator, by only partially opening and closing thedrawer, from causing the operation of the mechanism to do otherwisc thanregister and record the amount for which the proper keys are depressed.

In completing the opening movement of the 1 drawer it passes the shoe7L2, thereby permit l ting the spring of the arm It to depress the rodhand return the lever F to its normal position. By closing the drawer Athe lever l in being forced back against the tension of itscontrolling-spring Z encounters the dog 1' on the carriage-leverrthereby turning it to draw back the carriage to its initial position andtension the spring 0' for subsequently moving the carriage. By thebackward turning of the lever Z the rack Z rides bacluvard against thepinion m, thereby turning it freely through two revolutions withoutmoving the shaft in and bringing the dog m again coincident with thenotch in to be ready for turning the shaft when the drawer is againopened. By returning the carriage to its normal position the teeth r onthe rams are all removed out of engagement with the segmental racksD,thereby leaving them with out support, so that they return to theirnormal positions by the weight of the slotlinks D, which causes them todrop, carrying with them the arms 0 to their normal position. Indropping, the teeth 0 on the slot-links slip over the teeth of theratchets n in their paths without turning the ratchets, owing to theresistance to their turning afforded by the spring brake-teeth ofengaging the flutes in the rod it. Moreover, the slot-links yield indropping by the resilient give in the springs bearing against the lowermembers of the pairs of bell-cranks 0.

I have also provided in this machine for causing it to register bysubtraction and record amounts paid out, and also to furnish records ofcredit-sale amounts. For the iirstnamed purpose the following mechanismis provided:

K is a springkey supported in the front wall of the case near theleft-hand side of the machine,within which it passes freely through abearing 3 Toward its inner end this key is beveled to render itcam-shaped on its under side. A pair of levers L L, fulcrumed on a rodf, are connected together at their lower ends by a rod f, extendingacross the plane of the series of segmental racks D. One of these leversL is in the form of a bell-cran k turned up and forward toward the lowerend of its shorter arm into an expanded lip f which bears at its edgeagainst the cam-surface of the paid-out key K. On the top of the bearingis pivoted a dog f which depends into contact with the back or top ofthe key K, in which are provided at a proper distance apart two notchesf and f, in line with each other, for engagement with the dog. An arm fextends from the dogf into the path of and over the finger h on thethrust-rod 7/, to be tripped by the rise of that red.

M M are heads of general segmental form, terminating in stems M. One ofthese heads is fastened to a side of each segmental rack D and itsextension 0 through elongated slots 0 w therein in a manner to afford tothehead M and its stem a limited movement independent of the segmentalrack, on which it supported. The connecting-rod f of the two levers L Lbears against the backs of the heads M, and the stems M bear at theirextremities against curved fingers 0, depending from the angle portionsof. the upper bell-cranks 0", on which the slotlinks D are carried.

On the rod 0 is fulerumed to extend in the plane of the lever F an armN, connected by a link f with the long arm of the bell-crank lever L andterminating in a segment-shaped legend-bearing head N, the legend-mattershown being the words Cash, Credit, and Paid Out, formed,preferably,with perforating-points and arranged at equal distances apartacross the head. The uppermost word, Cash," is normally in the positionin dieated in Fig. 2, wherein it perforates the paper G, as shown on thecheck I in Fig. 1!), whenever the lever F is actuated while the arms 0*are in the position to which they are turned to perforate the paper,withthe amount of a sale registered on the wheels n by turning them in themanner already described.

When an amount is to be paid out of the machine, the proper keys A arefirst depressed in the order explained, thereby effecting in the mannerhereinbefore described movements of the carriage B to bring one or moreprojected rams in proper order into engagement with the respectivenumberof segmental racks I). Then the key K is pushed, clearing the dogf from the forward notch f in the key, and when the key has been pushedin so far as to cause the rear notchf to coincide with the dog thelatter engages it to hold the key against retraction under the recoil ofits controllingspring. 3y pushing in the key K the engagement of itscant end with the lip f swings the bell-crank L in the direction to turnthe arm N far enough to bring the final words Paid out on its head Ninto coincidence with the recess 7r. of lever F. The further result ofpressing the key K is to press the connecting-rod f against the heads M,and thereby force their stems M against the row of bell-crank fingerso". This action pulls forward the series of slot-links B to bring theirteeth o into position to engage the teeth of the respective ratchets a"when the slot-lin ks are raised. The next step in the operation is toopen the drawer, with the effects of actuating the apron m to push eachof the projecting rams back in its groove in the carrmge, raising thecorresponding number of slot-links to engage their teeth o with therespective ratchets n" to turn the latter backward, and bringing thearms 0 into position relative to the lever F to expose to the paper Gthe amount paid out. This amount 1 is obviously shown by subtraction onthe register as the remainder of cash in the machine. In the openingmovement of the drawer. the thrust-rod 72 is raised, thereby IIO causingthe linger 7/." to trip the dog f" and permit the key K to be returnedby its spring to normal condition and actuating the lever F to press thepaper for the check I against the perforating matter coinciding with therecess 7.2 on the heads of the arms o and N. Of course when the key Hreturns to its initial position the lovers L L are released to permitthem to resume their normal position and return there the arm N, as alsoto permit the heads hi and stems M to resume, un-

derthe forceof the springs which press against the bellcranks o ,-theirnormal position, and the slot-link D to right itself with relation toits ratchet of by bringing the teeth 0 into the plane of theratchet-teeth. It will be noticed that the surfaces of the heads Magainst which the rod f bears are formed on a circle, whereby the rodalways bears against them in any position to which they are turned byturning the racks D. Closing the drawer rcturns the carriage B to itsinitial or normal position and frees the one or more raised slot lin ksD to permit dropping thereof by gravity without effecting the registerand return to its normal position each segmental rack l) and arm 0 thathas been actuated.

To record a credit sale the key K is pro vided. This key is formed likethe key K that is, cam-shaped at its inner end, where it bears againstthe lip f of the bell-crank lever L; but it is shorter and has a shorterthrow than the paid-out .key and is provided with the notches f and jfor engagement by the dogf and accordingly closer together than thenotches in the longer key. By pressing in the key K its cam end turnsthe levers L L at the lip/' only enough to swing the arm ii so far as tobring the intermediate word credit on its head N into coincidence withthe paper-crossed recess 7.: of the lever i At the same time thepressure of the connecting-rod f against the heads Ill advances thestems M only sufficiently against; the fingers 0 to turn the bell-cranks0* far enough to center the slot-links D with reference to the ratchetsn", so that the latter will be between the planes of the slot-link teethand will not be touched by them in the rise of the slot-links in orderthereby to avoid disturbance of the register when the amount of thecreditsale is recorded. This is done by depressing, previous tooperating the key K, the key or keys A, representing the amount to berecorded, thereby setting the carriage l3 and proper number of rams B.By then opening the drawer the ram-returning action ensues, with theaccompanying setting of the arms 0 to present the amount of the sale tothe paper-crossed recess 7; of the lever i and accompanying rise of theone or more slot links D, though without any action of the latter uponthe register E, and the linal movement of the drawer in opening raisesthe rod h to actuate the recording-lever l and trip the dog 1" byengagement therewith of the finger 72 to permit the key K to return toits normal position. The effect of closing the drawer is to return inthe manner hcrcinbcfore described the carriage, each raised slotlink,and the arms o and N to their respec tive initial positions.

At desired periods the rings 12 of the register-should beset; to O.Toenablethistobc done with facility, l provide in corresponding positionon the rim of each ring a tooth d. A stop-lever (1, having a handle (I?extending along its back, is fulcrumcd between arms (1, projectingforward from the back of the case. This lever is normally in raisedposition. On opening the cover It and dropping the lever d the operatormakes a note of the amount shown by the register as being contained inthe machine. Then by gripping with the hand under the segmental heads ofthe arms 0 and turning them forward the four slotlinks I) are raised toengage their teeth o"- with the ratchets n in their paths, and therebyturn each wheel n controlled by a slotlink till its tooth (Z strikes thestop-lever d and is arrested at O. The several rings 01* at the left ofthe series thereof controlled by slot-links may each be moved back to 0by turning them by hand until their teeth d strike the stop-lever. Onreleasing the arms 0* the slot-links fall back to normal position.

In Fig. 26 is shown a modified construction of the mechanism undercontrol of the keys K and K. By this modification the heads 1i. andtheir stems M, as also the lingers 0" on bell-cranks o", are dispensedwith, and the teeth 0" of each slot-link l) are provided on a separatesection 0 yieldingiy sruiiported in position by connection at itsopposite ends with the extension o of the rack D by parallel links 0 o,the upper one of which has a rcarward-extended spring-pressed linger 0,bearing norm ally against a stop 0". The bank of rings, ratchcts, anddisks on the rod n and forming the register E are carried on arms 0 andc, at the upper ends of which the rod 7/. is supported at its ends, thearms being pivoted at their lower ends on bearings c projecting from therear wall of the case. The backward movement of the arms c c is limitiedby stops 0 on the rear wall of the case to be engaged by projections con the backs of the arms. In this connection only the le ver L of thetwo lovers L L is required, and it is connected from its longer arm by alinkbar I) with the arm n. By this modilied construction each slot-linkI), being formed integral with the correspondingrack D and arm 0,maintains always the same relation to the center at the rod 0, and theteeth 0 yield when the slot-link drops. The register itself, however, isadjustable with relation to the slot links, its normal position beingthat shown in which the ratchets it) are in the path of the teeth o Tobring the ratchets in the path of the teeth o for the subtractingfunction, the key K is operated to throw the register, as far aspermitted by the stops 0, back by the connection of the lever L with thearm
